Title: Immersion heater controller
Inventor: DAY STEPHEN
IPC: H05B3/78
Filed: 1984-01-23
Abstract: The coil 1 and normally-open contacts 3 of a current operated relay are connected in series with a thermostatically controlled immersion heater 2 so as to give a once-only heating of a hot water tank. A switch 4 is spring biased to a centre position from which it can be moved to a position bypassing the contacts 3 to initiate energization of the heater 2, or to a position shunting the coil 1 to thereby cause the contacts 3 to open and the heater 2 to be turned off.

Title: Telephone traffic measurement
Inventor: NEWSTEAD DENNIS PERCY
IPC: H04M3/36
Filed: 1984-08-14
Abstract: Traffic measurement, especially in a PABX, is effected by radio to avoid interference with the installation. To do this each line has a telephone set unit with an inductive sensor (1) which detects all connection attempts, whether outgoing or incoming and stores information relating thereto in a store 3. A block of such telephone units are polled, e.g. once per 10 seconds, by radio from a command unit, where the addresses of the lines served are repetitively generated by an address generator and sent by radio to the telephone set unit. Each set unit responds to its address and if its store (3) contains details of a call which has been completed, that message is sent to the command unit. Here it is decoded and stored in a store unit, from which such messages are sent typically via a modem and switching equipment to a central traffic analyser. In a large PABX a number of such command units each serving a block of lines is used. <IMAGE>

Title: Electromagnetic acoustic wave generation and detection
Inventor: SMITH DR BERNARD JAMES
IPC: G01H11/04
Filed: 1986-12-02
Abstract: A method of generating or detecting acoustic or ultrasonic waves in a solid object (10) which may be non-metallic, or non-ferromagnetic, involves coating the surface (11) with a layer (12) of magnetostrictive material such as powdered black ferric oxide in paint, which is left to dry hard. A varying magnetic field in the layer (12), caused by a current in a coil (16), causes ultrasonic waves to propagate in the object (10). Equally, an ultrasonic wave in the object (10), (e.g. reflected from a defect in the object), which causes mechanical oscillation of the layer (12), will induce a current in the coil (16), and the e.m.f. generated by the coil is detected (20). <IMAGE>

Title: Line clipping for a viewport display
Inventor: TREVETT NEIL FRANCIS
IPC: G06T15/10
Filed: 1988-03-23
Abstract: A line having two directional components and a given length is clipped to display only a predetermined segment of the line by initializing any of a multiplier accumulator's output registers 410, 412, 414 with a predetermined intial value; loading a first input register 402 of a multiplier accumulator with the value of one component of the line; loading a second input register 404 of the multiplier accumulator with the value of the reciprocal of the other component of the line; causing the multiplier accumulator to multiply 406 the values in its first and second input registers; repeatedly adding the fractional part of the multiply to the first output register 410 while adding the overflow of the first output register in a second output register 412; repeatedly adding the integer part of the result of the multiply to the second register 412; and, drawing a point on a display device whenever the value in the second output register changes. The reciprocals for register 404 may come from a look-up table (502, fig 5). This method uses simple hardware, avoids divide operations and addresses the "Subset line" problem. <IMAGE>
